Effects of separate and intergrinding on some properties of portland composite cements
Soyluoğlu, Serdar; Tokyay, Mustafa; Department of Cement Engineering (2009)
In the production of cement, to increase the cement/clinker ratio and decrease CO2 emission, the most important alternative is to produce mineral admixture incorporated cements (CEM II-III-IV-V) instead of portland cement (CEM I). These cements are usually produced by intergrinding the portland cement clinker and the mineral admixtures. However, the difference between grindabilities of the different components of such cements may cause significant effects on the particle size distribution and many other pro...
Effect of trass, granulated blast furnace slag and fly ash on delayed ettringite formation
Topbaş, Selim; Tokyay, Mustafa; Hoşten, Çetin; Department of Cement Engineering (2010)
Properly proportioned, placed and cured concrete can be durable under most conditions. However, deterioration of concrete does occur under certain environments. One of the problems that affect the durability of hardened concrete is delayed ettringite formation (DEF) which is an important problem encountered in precast concrete industry where high temperature curing is applied. Although there had been many researches on DEF, there are still many uncertainties about its chemistry and mechanism. In this study,...
Development of magnesium potassium phosphate cement pastes and mortars incorporating fly ash
Bilginer, Baki Aykut; Erdoğan, Sinan Turhan; Department of Civil Engineering (2018)
Magnesium potassium phosphate cements (MKPCs) have some promising properties to be considered as an alternative to ordinary Portland cement binders. The favorable properties of these cements are high early and ultimate strength. On the other hand, they have some problems like rapid setting, high heat of reaction, high cost and poor water stability. In this study, the effect of several factors like magnesium-to-phosphate molar ratio (M/P), water-to-binder ratio (W/B) and retarder (borax) content on propertie...
